Sharing more details about recurring transactions, Kristopherts.

In QuickBooks Online, we can only assign one recurring invoice into one customer. What I can suggest is to create a duplicate recurring invoice and change the customer. From the Recurring Transactions page, locate the invoice. Then, click the drop-down and select Duplicate. On the Invoice page, change the Template name and the Customer. You can also make other changes before clicking Save template.

You can pull up the Recurring Template List report if you need reference. This will show all the recurring transactions you've created in QuickBooks Online.
